What is Kubernetes?

Kubernetes is an open source platform for orchestrating and managing container applications. Today, a Kubernetes project plays a crucial role in the efficient deployment, scaling and management of applications in a container environment.

Originally developed by Google, the open source system Kubernetes may seem like a technical term at first, but it represents more than just a technology – it stands for the flexibility, scalability and efficiency that companies need to manage their infrastructures and future-proof applications. It also enables companies to deploy and manage their (cloud) applications more efficiently, regardless of the existing infrastructure.

Kubernetes simply explained

Imagine Kubernetes as an intelligent city administration. There are different buildings in a city – these are the applications or services. Kubernetes works like an administration that takes care of these buildings. It ensures that they are placed correctly, have enough resources and function smoothly. Similar to how a city administration regulates traffic, Kubernetes coordinates the data traffic between the container applications and ensures that everything runs stably, even if parts fail. In short: Kubernetes is a smart solution for organizing and managing applications in large data centers or the cloud.

A Kubernetes cluster is a group of interconnected computers or servers that work together to run Kubernetes to manage container applications. There are different types of nodes within this cluster:

• Master node: This acts as the control center of the cluster and coordinates all activities. It manages the status of the cluster, receives commands and distributes the work to the “worker nodes”.
• Worker nodes (nodes): These are the computing resources on which the actual applications are executed in containers. They receive instructions from the master node and execute the containers according to the specifications.

A Kubernetes cluster enables the management and orchestration of container applications across a distributed environment. The nodes work together to facilitate the execution, scaling, maintenance and operation of applications. By distributing workloads across different nodes and automatically detecting failures, the cluster ensures high availability and robustness of applications. Overall, the Kubernetes cluster forms the basis for the efficient management and provision of container applications in a scalable and stable environment.

Kubernetes has become a central technology for container orchestration and is widely used in various digitalization processes. This platform is not only used in the cloud, but also in data centers and hybrid environments and offers a wide range of benefits. Its improved efficiency, scalability and greater resilience make it an indispensable tool for companies in various industries.

• Scalable applications: Kubernetes is ideal for companies that want to develop and operate individual applications. It enables easy scaling of applications by automatically creating new instances of applications to handle increasing loads and scaling them down again when the load is low.
• Microservices architecture: Companies that use a microservices architecture benefit from Kubernetes. It offers the option of dividing applications into smaller, independent services and managing and updating them flexibly.
• Continuous Integration/Continuous Deployment (CI/CD): Kubernetes plays an important role in the CI/CD pipeline. It enables the automation of development processes, from the deployment of new code changes to the updating and delivery of applications. We make use of this advantage for our KUBE-X development platform. Find out what benefits this has for our customers here.
• Big data and analytics: For companies that perform complex data processing and analyses, Kubernetes offers a flexible environment for the provision and management of big data workloads. It enables resources to be scaled according to data processing requirements.

Advantages

• Mobility: Thanks to its portability, applications can be easily deployed on different infrastructures such as public clouds, private clouds and local data centers.
• Resilience: Kubernetes offers mechanisms for resilience. It can automatically detect and respond to failures by redirecting workloads to other healthy nodes to ensure application availability.
• Efficient resource utilization: By effectively managing resources such as CPU, memory and network resources, Kubernetes optimizes infrastructure utilization, resulting in better resource utilization and cost efficiency.
• Automation and orchestration: Kubernetes automates many aspects of application management, such as deployment, scaling and updating applications. This enables efficient orchestration of containers and applications.

1. cloud-native applications: Kubernetes is designed to orchestrate and manage cloud-native applications. The cloud provides the infrastructure on which Kubernetes can run and enables flexible scaling and resource provisioning for applications. Kubernetes makes it easier to deploy applications in the cloud.

2. multi-cloud support: Kubernetes enables the support of applications across different cloud providers. Organizations can easily move their applications between different cloud platforms or run them in a multi-cloud environment because Kubernetes provides a consistent orchestration layer.

3. resource optimization and scalability: The cloud provides the ability to scale and utilize resources as needed. Kubernetes facilitates the efficient management of these resources by enabling the automatic scaling of applications based on current resource requirements.

4. integration of cloud services: Kubernetes can be seamlessly integrated with various cloud services to incorporate additional functions such as storage, networks, databases or AI services into applications. This allows companies to benefit from the numerous advantages and possibilities of the cloud.

The future of Kubernetes sees increased integration with other technologies such as artificial intelligence (AI), edge computing and serverless computing. Kubernetes is expected to further cement its role as a central component of modern application development.

1. edge computing and IoT integration: The increasing adoption of edge computing and Internet of Things (IoT) will increase the demand for efficient orchestration and management of applications in distributed locations. Kubernetes is expected to play a critical role in scaling and managing applications at edge locations to bring computing power and application logic closer to end users.

2. integration of AI and machine learning: Kubernetes will be increasingly used in AI and machine learning applications to manage complex workloads. The integration of machine learning tools and frameworks into Kubernetes ecosystems is expected to facilitate the use of AI in various industries using Kubernetes.

3. further development of security functions: As the attack surface for cyber threats increases, security in Kubernetes clusters will continue to gain importance. Future developments will aim to implement robust security measures and policies to protect data and applications in Kubernetes infrastructures.

4. improving user-friendliness and user experience: The further development of user interfaces, tools and dashboards for Kubernetes will help to improve user-friendliness. It is expected that the simplification of operation and the provision of intuitive tools will further increase the acceptance of Kubernetes.

5. development of specific application and industry solutions: Industry-specific requirements and use cases will lead to specialized solutions and industry standards.
